SHUTTLE FOR LOOMS.

SPECIFICATION formingpart of Letters Patent No. 630,793, dated August 8, 1899.

Application filed March 20, 1899. Serial No. 709,818. (No model.)

To all whom it may concern:

Be it known that I, ADJUDEUR Arms, of \Voonsocket, county of Providence, State of Rhode Island, have invented an Improvement in Shuttles for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates more particularly to self-threading shuttles .for looms of that type wherein a filling-carrier is automatically supplied to the shuttle Whenever for any reason the weft fails to be properly laid in the shed-- as, for instance, in United States Patent No. 529,940, dated November 27, 1894, wherein the fresh filling-carrier is inserted in the shuttle at one open side and by its entrance acts to eject from the opposite open side of the shuttle the spent filling-carrier. It has been found in practice that when such looms are run at high speed the tip of the filling-carrier sometimes is deflected to one side as it enters the shuttle, so that the holding means carried by the shuttle does not firmly engage the head of the filling-carrier. More frequently the tip of the ejected filling-carrier will deviate from its proper path and the filling-carrier will twist or move into a position at an angle to the longitudinal axis of the shuttle, interfering with the proper entrance of the fresh filling-carrier or otherwise obstructing the proper operation of the parts.

In my present invention I have overcome the before-stated objectionable features by providing the shuttle with a support or stop for the tip of the filling-carrier when the latter is ejected, to thus always insure the discharge of the filling-carrier head downward,

a narrow guideway in the shuttle-body leadthreading shuttle embodying my invention, with a filling-carrier in place therein, the filling omitted for the sake of 'clearness. Fig; 2 is a side View thereof, partly broken out to show the tip-support or stop and the guideway leading thereto; and Fig. 3 is a transverse sectional view of the shuttle on the line to as, Fig. 1.

The shuttle B, the holder comprising jaws O, notched or grooved at their inner sides to be entered by ribs or projections d on the head 01 of the filling-carrier D, shown as a copskewer, and the self-threading device T are and may be all of usual or suitable construction.

The shuttle is shown as open at its top and bottom, and at its forward end I form a longitudinal narrow slot or recess 1), open at its inner end and extending from the top of the shuttle toward its under side, forming a guideway with vertical side walls, leaving a support or stop b at the bottom of the guideway in the plane of the longitudinal axis of the shuttle and at or near its under side. At its upper end or entrance the guideway b may be made slightly flaring, as at to facilitate the entrance of the tip of the filling-carrier D thereinto.

When a full filling-carrier is inserted in the shuttle, its tip enters the narrow guideway 19 and is thereby maintained in proper position to enable the head d to accurately enter and be engaged by the holding means 0. Should the projections on the head of the incoming filling-carrier fail to register with the grooves in the jaws, then the support or stop I) will engage the tip of the filling-carrier and prevent it from descending below the under side of the shuttle.

When a spent filling-carrier is about to be ejected from the shuttle, the tip is held by the support I), so that the head will descend first and at the same time the adjacent sidewalls of the guideway I) act to position the tip and prevent its lateral deflection, so that the ejected filling-carrier will pass properly and without catching through the discharge slot -or opening in the bottom of the shuttle-box.

The support or stop also serves to prevent the dropping of the tip of the filling-carrier when the shuttle is in motion should the head become loosened in the holder.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

A shuttle-body having holding-jaws to receive and frictionally engage the head of a removable filling-carrier and permit it to be discharged therefrom at the side opposite that at which it enters the jaws, a support or stop located in such position as to be struck by the tip or delivery end of the filling-carrier
